Financial transactions credit note

You may amend the gstr1 now it self

For you to disclose the credit note, you have to issue invoice. But in the instant case, invoice is issued by supplier and even debit note issued thereafter. That's the reason there is error displayed that original invoice not found.. you have never issued original invoice.. you are recipient. There is no need for you to issue credit note ideally.. just avail the ITC of gst recorded in debit note issued by supplier.

The Inward supply are not reported in GSTR 1 , hence the credit for the same from Supplier , you need to Reverse the ITC .
Hence such transactions need to report in GSTR 3B by reducing it from the total ITC for the month .

Sir i not raised invoice and shall I not to add credit note in gstr1 ?
